(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. 14.,1313.)

To all whom it may cmwemi Be it known that I, BELA PALLAVIOINI, anAustrian citizen, residing at Gusshaustrasse 17, Vienna 4, Austria, haveinvented certain new and useful Improvements in or Relating toShock-Deadenin Ball or Roller Bearings (for which I have ed applicationsin Austria, Dec. 18,1919, Patent #88140, of March 15, 1921; Germany,Dec. 29, 1919, Patent #335,144, Dec. 30, 1919; Czechoslovakia, Dec. 22,1920; Sweden, Dec. 29, 1920; France, Dec. 30, 1920, Patent #534,838,Dec. 30, 1920;-Great Britain, Jan. 10, 1921, Patent #157731, Jan10,1921; Italy, Jan. 14., 1921), of which the following is a specification.

This invention relates to shock deadening ball or roller bearingsespecially applicable to bearings for-vehicles having the vehiclesupport excentrically disposed with regard 2 to the hub of the vehiclewheel. In this type of bearing it is usual to provide an excentricinterposed between the member sup? porting the vehicle and the hubmember and to provide inner and outer rings of balls between said hubmember, said excentric and said supporting member, but in all knownconstruct-ions the sets of inner-and as possible the inner and outerrings of balls situated between the hub member, theexcentrio and thesupporting member are arranged out of line with each other, and theirexcentric position maintained by ribs and constrictions provided on theexcentric and likewise arranged out of line with each other.

In the drawings, Fig. 1 is an axial section through a ball bearingembodying my invention, intended for a front wheel.

Fig. 2 is an axial section through a bearing for a rear wheel.

Fig. 3 is a section on the line A-B of Fig. 1, an

Fig. 4 is a section on the line CD of Fig. 2.

he ball bearing consists of the bearing rings 6, 0 arranged around thesupporting axle of the vehicle and held apart by a (liS-' in order toobtain as compact a construction tance sleeve 0. In the hub of the wheelare placed the bearing rings 7;, j se arated by a distance sleeve 7 andserving or the outer rings of balls 9, h. The corresponding rings ofballs e, h and d, g, respectively are arranged out ofline with eachother and receive their excentric positions through a rib Z andconstrictions m provided on an excentric is situated between the ringsof balls, there being a pair of ribs Z and constrictions m on theeccentric k ad'acent each end thereof. A rib Z on one si e of the axismer es gradually into its cooperating constriction m to form the bearingsurface for each set or ring of balls and they are so distributed onthe. excentric that, there is situated alongside the rib Z for one ringof balls (2 or e the constriction m for the other ring of balls 9 or it,or vice versa. By this means there is provided, the excentricity asbetween the axes I and II of the inner and outer rings of ballsremaining constant, a reduction of the diameter of the outer ring ofballs, as small a wheel hub as possible and a compact construction ofthe arrangement.

In the case of ball bearings intended for the rear wheels (see Figure 2)the excentric k is preferably extended at one end so as to form a meansfor attaching the brake shoes to the wheel, the construction of thismeans forming no part of the present mechanism not being shown in thedrawing.

What I claim and desire to secure by Letters Patent of the United Statesis l. A shock deadening ball bearing for, ve-' hicles comprising acentral sleeve having a plurality of ribs and constrictions formed onits inner and outer surfaces to provide'a plurality of inner and outerball races, eccentrically disposed with respect to the axis of saidsleeve, each of said ballraces being defined by a rib and a cooperatingconstriction in alignment therewith, and a ring of balls interposedbetween said inner races and the axle of the vehicle and a ring of ballsinterposed between each of the outer races and the wheel hub.

2. A shock deadening ball hearing as set forth in claim 1 in which saidball races are set out of alignment with one another whereby the outerdiameter of the bearing is reduced to provide a compact structure.
